[vtkusers] Java remove vtkImageViewer2 not working

[Jonathan Morra]

I have a java swing JPanel that contains another JPanel that contains a
vtkRenderWindowPanel which is hooked up to a vtkImageViewer2. In the course
of my program I want to remove the inner JPanel from the outer JPanel with
JPanel.remove(). I then want to add the inner JPanel to a different outer
JPanel. However when I do this VTK throws the following exception

ERROR: In ..\..\src\Rendering\vtkWin32OpenGLRenderWindow.cxx, line 247
vtkWin32OpenGLRenderWindow (00000004C8E4830): wglMakeCurrent failed in
MakeCurrent(), error: The handle is invalid.

This seems like a very simple swing operation that I'm trying to do, but
it's failing. Does anyone know what I'm doing wrong?
Thanks
